Looking at the size of the triangles in the quilt, however, I think it's going to be much easier to get the correct ruler. Creative Grids has a 12" version.
I want to shout, too, about this.
The Tri-Recs Ruler is made for the triangle in a square unit (Peaky and Spike - Doreen Speckmann).
The angles in a Tri-Rec Ruler Set are:
Small triangle: (approximately) 26.565, 90, and 63.435 degrees
Large triangle: (approximately) 63.435, 63.435, and 53.130 degrees
At one time I thought that the 30-60-90 or 60-60-60 degree rulers were interchangeable with the Tri-Rec rulers.
They are NOT.
